Use hormone therapy.
Don't use hormone therapy. Take non-steroidal anti-inflammatory drugs (NSAIDs) for mild pain if your doctor says it's okay.

This decision aid is for women who have mild symptoms and have not yet had laparoscopic surgery to diagnose or treat endometriosis. Hysterectomy and oophorectomy may be an option for women who have severe symptoms and have already tried hormone therapy and laparoscopic surgery.

Key points to remember

There is no cure for endometriosis. But hormone therapy can help relieve pain.
Hormone therapy is a good first choice for treatment, unless you want to get pregnant soon. Hormones may reduce the number and size of growths (implants) and keep them from spreading.
When your menstrual periods stop at around age 50 (menopause) and your estrogen levels drop, endometriosis growth and symptoms will probably also stop. (In some cases, scar tissue remains after menopause and can cause problems.)
Several hormones may be used. You would start with birth control hormones (such as a patch, pills, or a ring). They are usually the best choice for long-term use until menopause. If they don't help your symptoms, you could move to a stronger hormone. And if that one didn't help, you might try an even stronger hormone. The stronger hormones are often used only for a short time, because they have serious side effects.
If your doctor says it's okay, you can take non-steroidal anti-inflammatory drugs (NSAIDs) with or without hormone therapy to help your pain. Be safe with medicines. Read and follow all instructions on the label.
For some women, hormones reduce pain for only a short time. For others, relief lasts a long time.

FAQs

What is endometriosis?

The endometrium is the tissue that lines the uterus. During each menstrual cycle, a new lining grows, getting ready for a possible pregnancy. If you don't become pregnant during that cycle, the lining sheds. This is your menstrual period.

Endometriosis (say "en-doh-mee-tree-OH-sus") occurs when tissue that is similar to the endometrium grows outside of your uterus. It usually grows on the ovaries or the fallopian tubes. It also may grow on the outside surface of the uterus, the bowels, or other organs in the belly.

These growths are called "implants." They grow, bleed, and break down with each menstrual cycle, just like the lining of the uterus does. In some women, this can cause pain and can make it hard to get pregnant.

Sometimes scar tissue forms around implants. This also can cause pain and trouble getting pregnant.

The female hormone estrogen, released by the ovaries, makes the implants grow.

How will endometriosis affect you?

While some women never have symptoms, others have severe pain. In some cases, the problem can affect how well your bowels, bladder, or other organs work.

Pain from implants may be mild for a few days before your menstrual period. It may get better during your period. But if an implant grows in a sensitive area such as the rectum, it can cause constant pain or pain during sex, exercise, or bowel movements.

Symptoms often get better during pregnancy and after childbirth and usually go away after menopause.

How do you take hormone therapy?

You likely will start treatment with birth control hormones. They are usually the safest hormones for long-term use. If they don't help your symptoms, you could take a stronger hormone. And if that one doesn't work, you could try an even stronger hormone. The stronger hormones are used only for a short time, because they have serious side effects.

Hormone therapy reduces estrogen levels in your body. Because of this, you can't use hormone therapy if you want to get pregnant.

Birth control hormones (such as a patch, pills, or a ring) stop ovulation and the growth of implants. These hormones can be used long-term until menopause.
Gonadotropin-releasing hormone agonist (GnRH-a) therapy lowers estrogen to the levels women have after menopause. It's usually used for only 3 to 6 months. Women sometimes take it with progestin to reduce side effects. GnRH-a is given as a shot or as a nasal spray.
Progestin lowers estrogen. It shrinks implants and reduces pain. Progestins are given as a shot or a pill. The levonorgestrel-releasing intrauterine device (LNG-IUD) is also used.
Danazol lowers estrogen levels and raises male hormone (androgen) levels. It shrinks implants and reduces pain for most women. Because of its side effects, though, it is not chosen as often as the other hormones. And it's used for no more than 6 to 9 months.
Aromatase inhibitors help stop the body from making estrogen. These medicines are used along with hormone treatment.

How well does hormone therapy work?

Hormones relieve the symptoms of endometriosis for many women. You may have to try two or more types of hormones before you find one that works for you.

If taking birth control hormones works for you, you can use them for years (unless you plan to get pregnant).

For some women, hormones work for a while. For others, relief lasts a long time.

After treatment with any hormone therapy, pain may come back.

What are the risks of taking these medicines?

These medicines have different side effects and risks. Some of them can make you feel like you're going through menopause.

Birth control hormones. Side effects are usually mild and often go away after the first few months. They can include spotting between periods, nausea, headaches, breast tenderness, and mood changes. There is a small increase in the risk of getting blood clots. Your doctor will not prescribe these hormones if you have had blood clots before, have had breast cancer, or are older than 35 and smoke.
Gonadotropin-releasing hormone agonist (GnRH-a). Side effects can include hot flashes, mood swings, vaginal dryness, less interest in sex, trouble sleeping, and headaches. Risks also include bone thinning.
Progestin. Side effects may include mood changes and depression, bloating and weight gain, weight loss, breast tenderness, and absent or light and irregular periods. High-dose progestin can cause bone thinning. Talk to your doctor about whether the progestin intrauterine device (Mirena) might give you the same benefits with fewer side effects.
Danazol. Side effects include decreased breast size, acne, and more facial and body hair. It can also cause deepening of the voice, which can be permanent. It can increase the risk of "bad" cholesterol.
Aromatase inhibitors. They can cause headaches, nausea, diarrhea, aching joints, and hot flashes. You also have a risk of bone thinning if you use these medicines for a long time.

Why might your doctor recommend hormones to treat your symptoms?

Your doctor may advise you to try hormones if:

Your symptoms are mild.
You are close to menopause. Hormones might ease your symptoms until menopause.

Personal stories about treating endometriosis with hormone therapy

These stories are based on information gathered from health professionals and consumers. They may be helpful as you make important health decisions.

The pain before and during my periods was so bad, I couldn't exercise. I am an active person, and the pain was really getting me down. I have had endometriosis for years and have tried ibuprofen and other medicines I could get at the drugstore, but they were not helping anymore. My doctor said taking birth control pills might help me. She said that also taking ibuprofen around the time of my period could really help. After a couple of months, I noticed enough of an improvement that I could do everything I used to. I'm especially happy that I can use this treatment for a long time, unlike other hormone therapies like Lupron.

Maria, age 45

I first noticed that my periods were becoming painful about a year ago. I wasn't too concerned, but I discussed the pain with my doctor when I went for a Pap test. My examination and Pap test were fine. My doctor said that endometriosis could be the cause of my pain. Since my mom and an older sister have had endometriosis, I wasn't too surprised. My doctor talked to me about my options. She told me that using ibuprofen, such as Advil or Motrin, might help my pain. Now I start taking ibuprofen the day before my period begins. It really helps relieve my pain. As long as ibuprofen helps my pain, I will wait before I try other treatment for my endometriosis.

Kathleen, age 38

I was surprised when my doctor told me endometriosis could be the cause of the pain I was having with my periods. I had never heard of endometriosis before. He explained what it was and told me about the treatments I could try. Taking birth control pills didn't help, and my doctor said a medicine called Lupron might stop the pain, though I could only take it for a few months. Treatment with Lupron worked. I hardly have any pain now, and taking a little estrogen for add-back therapy controlled the hot flashes without feeding the endometriosis.

Hannah, age 29

My periods were really painful about 5 years ago. I went to my doctor, and he asked a lot of questions about my periods and did a pelvic examination and some tests. When all the tests came back normal, he said endometriosis might be the cause of my pain. I asked if waiting a few months to decide about treatment would be dangerous. He said waiting would be fine. After a few months, the pain eased up. I am glad I decided to wait and see.
